The process of how organisms acquire adaptations over time is called this.
What is evolution?
100
Wisdom tooth is one of this
What is a vestigial structure?
100
In order for natural selection to occur populations must do this.
What is over-reproduce?
100
When a new population is formed by a founder.
What is the founder effect?
100
This is the evidence that is buried deep inside the earth
What are fossils?
200
Why do animals overproduce?
To increase chances of survival/ variation.
200
Bird's wing and butterfly's wing are examples of these
What are analogous structures?
200
Darwin concluded that the mechanism for evolution is this.
What is natural selection?
200
Mass extinctions are created by this
What are natural disaster, human activities, asteroids?
200
Fossils are the strongest evidence of evolution:True or False
What is True?
300
Whales evolved from this animal
What is a wolf like land mammal?
300
Vestigial organs provide a proof for this
What is evolution?

The climate of a certain area is cold, and snow is found on the ground most of the year. Equal numbers of two populations of rabbits are introduced into this climate by a group of scientists. One of the populations is brown and the other is white. Over several generations, this will happen.
What is there will be more white rabbits than brown rabbits?
300
Continental drift or clashes of continents can cause this to happen
What is mass extinction?
300
If our DNA is 99.9% similar to a Bonobo, then it means this
What is we had a common ancestor?
400
Species that share more similarities in their DNA are _____ than those that share fewer similarities.
What is more closely related?
400
Homologous structures have same ___________ but different __________.
What is structure and function?
400
Variations are important for this to happen
Survival of the fittest.
400
Genetic drift causes this to happen, therefore we can say evolution can take place
What is change in allele frequency?
400
Embryological evidence proves this
We share common ancestors with all vertebrates
500
Over 90% of the DNA base sequences for hemoglobin in chimpanzees and humans are identical, suggesting this.
What is that the two species share a common ancestor?
500
An example of homologous structure
Arms of vertebrates.

Natural selection is not the only way of evolution. The two other mechanisms of evolution are:
What is genetic drift, sexual selection or artificial selection?
500
A natural disaster can wipe out entire population and this is an example of: founder effect or population bottleneck
What is bottleneck?
500
Fossils found in the lowest layers of undisturbed rock are not found in upper layers of the same undisturbed rock. Explain what might have happened.
What is earlier species became extinct due to 1. The changing environments on Earth causing loss of habitat, increased competition, new predators, or catastrophes. 2. Lack of genetic variation within a species.
